Physalia Physalis Physalia physalis (bluebottles) taken as over/under images in Bushrangers Bay, NSW Australia. After strong NE winds hundreds of these potentially dangerous zooids are blown into the bays around Bushrangers and trapped overnight. What I really love about over/under photographs is that it gives the underwater element a sense of place. For the viewer it marries the underwater environment with our own familiar world. It links the unknown with the known. The bluebottles were lit with an Inon Z220 underwater strobe and fibre optic snoots. Post processing is limited to colour temp, minor cleaning and small amounts of dodging and burning.
